Answer 1

#include <stdio.h> //function to copy the string int copy_string(char *target, char *source) { //variable tp store length, it will also work //as loop counter int len=0; //loop to run from 0 (len=0) until NULL ('\0') //not found while(source[len] != '\0') { target[len] = source [len]; len++; } //assign NULL to the target string target[len] = '\0'; //return 'len'- that is number of copied characters return len; } //main code int main() { //declare and assign string1 to be copied char str1[]="This is a test string"; //declare string 2 as target string char str2[30]; //variable to store number of copied characters //that will be returned by the copy_string() int count; //calling the function count = copy_string(str2,str1); //printing values printf("Source string (str1): %s\n",str1); printf("Target string (str2): %s\n",str2); printf("Copied characters are: %d\n",count); return 0; }
